•半导体晶圆制造所使用的气体•CVDToolProcessGas•特气传输与控制•？半导体晶圆制造所使用的气体——特种气体分类 （3）腐蚀性气体（CorrosiveGas）这些腐蚀性气体通常同时也兼有较强的毒性。腐蚀性气体在干燥状态 下一般不易侵蚀金属，但在遇到水的环境下就显示出很强的腐蚀性，如HCl,HF,PCl3,SiF4,ClF3，...
一、MIG焊的基本原理定义：MIG焊（metalinertgaswelding）是利用外加的惰性气体作为电弧介质、利用焊丝作熔化电极的电弧焊。另:MAG例如：O2（2%~5%）+Ar 根据GB/T5185-1985《金属焊接与钎接方法在图样上的表示方法》，MIG焊的标注代号为131。二、MIG焊的特点 优点：①焊接质量好：保护气；过程稳定，变形小；飞溅...
